(short for polar aurora)--A glow in the sky, often observed in a ring-shaped region around the magnetic poles ("auroral zone") and occasionally further equatorward The name comes from an older one, "aurora borealis," Latin for "northern dawn," given because an aurora near the northern horizon (its usual location when seen in most of Europe) looks like the glow of the sky preceding sunrise Also known as "northern lights," although it occurs both north and south of the equator The aurora is generally caused by fast electrons from space, guided earthward by magnetic field lines, and its light comes from collisions between such electrons and the atoms of the upper atmosphere, typically 100 km (60 miles) above ground
Excitation of particles from the sun spiralling in the geomagnetic field near the poles resulting in the release of energy in different forms, including light
A glow in a planet's ionosphere caused by the interaction between the planet's magnetic field and charged particles from the Sun This phenomenon is known as the Aurora Borealis in the Earth's northern hemisphere and the Aurora Australis in the Earth's Southern Hemisphere
It is created by the radiant energy emission from the sun and its interaction with the earth's upper atmosphere over the middle and high latitudes It is seen as a bright display of constantly changing light near the magnetic poles of each hemisphere In the Northern Hemisphere, it is known as the aurora borealis or Northern Lights, and in the Southern Hemisphere, this phenomena is called the aurora australis
(a) The Northern (or Southern) Lights, a display of brightly coloured lights seen by observers near the Earth's poles due to the excitation of molecules in the Earth's atmosphere by the energetic particles in the solar wind (b) Goblin fireworks Earth is particularly famed as a provider of beautiful displays due to the abundance of nitrogen and oxygen in its atmosphere, which produce the red and green colours
It is created by the sporadic radiant energy emission from the sun and its interaction with the earth's upper atmosphere over the middle and high latitudes It is seen as a bright display of constantly changing light near the magnetic poles of each hemisphere In the Northern Hemisphere, it is known as the aurora borealis or Northern Lights, and in the Southern Hemisphere, this phenomena is called the aurora australis
a glow in a planet's ionosphere caused by the interaction between the planet's magnetic field and charged particles from the Sun
A faint visual (optical) phenomenon on the Earth associated with geomagnetic activity, which occurs mainly in the high-latitude night sky Typical auroras are 100 to 250 km above the ground The Aurora Borealis occurs in the northern hemisphere and the Aurora Australis occurs in the southern hemisphere
A glow in the sky, seen often in a ring-shaped region around the magnetic poles ("auroral zone") and occasionally further equatorward The name comes from an older one, "Aurora Borealis", Latin for "northern dawn," given because an aurora near the northern horizon (its usual location when seen in most of Europe) looks like the glow of the sky preceding sunrise Also known as "northern lights", although it occurs both north and south (Aurora Australis) of the equator The aurora is generally caused by fast electrons from space, guided earthward by magnetic field lines, and its light comes from collisions between such electrons and the atoms of the upper atmosphere, typically 100 km above ground

(Latin for "dawn") a glow in a planet's ionosphere caused by the interaction between the planet's magnetic field and charged particles from the Sun
A glow in the Earth's ionosphere caused by the interaction between the Earth's magnetic field and charged particles from the Sun (The Solar Wind) It gives rise to the "Northern Lights", or Aurora Borealis, in the Northern Hemisphere, and the Aurora Australis in the Southern Hemisphere
A faint visual phenomenon associated with geomagnetic activity, occurring mainly in the high-latitude night sky Typical auroras occur 100 to 250 km above the ground as high speed particles from the solar wind collide with atmospheric gasses at these altitudes When observed in the northern hemisphere this phenomena is known as the Aurora Borealis (northern lights), and when viewed in the southern hemisphere it is the Aurora Australis
